rdmsm4x changelog — Tyrell Build 13 ecs0 shared-runtime acceptance

Independent read-only acceptance completed for the pinned Tyrell/ecs0lib networking and logging candidates. Focused timeout, cancellation, privacy, and typed-logging evidence is green; no candidate is promoted because shared-owner acceptance and clean canonical publication remain absent.

Scope

Host: rdmsm4x
Project: Tyrell, Production mode
Scope: /Users/richh/dev/_worktrees/ecs0lib-build10-http-bounded-return-20260902 at afe50da605fcdd077a18120eaddc8d7e31e2d8f6; /Users/richh/dev/_worktrees/tyrell-build10-runtime-integrated-20260902 requested commit acf0818b1d1524009716efa355b96d455c51a822 (worktree tip a5b057e1ebf5a461740f9df4997bf8f9f9ee5dbf)
No source/worktree edit, merge, publication, service, deployment, credential, CloudKit, signing, or live-network mutation.

Acceptance handoff SHA-256: fccf8ed7424d7c18427a2725eadf6d36f222d05ff2bd7502ca9cf7ac4091ab6b.

Commands and evidence

Disposable ecs0lib copy: swift test --filter ECS0HTTPClientTests -> 14/14, zero failures; swift test --filter ECSPrivacyLoggingTests -> 7/7, zero failures.
Disposable Tyrell candidate mapping: TYRELL_ECS0LIB_CANDIDATE_PATH=/Users/richh/dev/_worktrees/ecs0lib-build10-http-bounded-return-20260902 scripts/verify_build10_usage_http_candidate.zsh --focused -> Build10SharedRuntimeCandidateCompatibilityTests 6/6, zero failures; disposable tyrellbar build passed.
Disposable Tyrell typed logging: swift test --filter PowerGovernanceCandidateLoggingTests -Xswiftc -DTYRELL_ECS0LIB_BUILD10_CANDIDATE -> 3/3, zero failures.
Source/worktree status checks before and after remain clean for both requested candidate branches.
Current canonical ecs0lib observed at 9f27867942024c5640f10c35d17d97ff2e6664f2 with six untracked ownerless path groups; candidate commits are not ancestors. Current canonical Tyrell observed at 25405a7a5b93c262dbdafdb7da84c9868382e652 and was not touched.

Decision

ECS0HTTPClient bounded-return: NO-ADOPT pending explicit shared-owner decision and clean canonical publication; Tyrell URLSession fallback/candidate guard stays.
Tyrell usage HTTP adapter: NO-ADOPT pending owner release plus post-publication full schema/freshness/last-good/fallback verification.
PowerGovernance typed logging: NO-NEW-ADOPT/PROMOTE. State-machine invariants pass and privacy is stronger, but output is intentionally not byte-identical (workload, return code, and assertion ID redacted/omitted) and candidate methods are async.
Remaining direct logging seams: NO-ADOPT; no closed accepted values-free API equivalent is available.

Backup and undo

No source or runtime state changed. The acceptance is reversible by retaining or deleting only the three generated handoff logs and acceptance packet; no canonical rollback is required. Candidate branches remain isolated.

Outstanding owner action

The shared ecs0lib owner must explicitly ACCEPT or REJECT the bounded HTTP repair and typed logging API, publish a clean canonical revision excluding unrelated untracked paths, and name the integration path. Tyrell then reruns focused/full/release gates and the separate signed rdmbair15m5 canary gate.

Checkpoint note

agent_checkpoint.zsh was attempted for the milestone but exited bad substitution; the ticket comment on TASK-20260902-09 records the milestone and resumption action.
